Abstract
The purpose of the present invention is to establish a more precise method for evaluating long-run moldability and, based on this method, improve long-run moldability of a resin composition containing an EVOH-based resin and a nylon 6-based polyamide. Provided is a resin composition having improved long-run moldability and containing an EVOH-based resin and a nylon 6-based polyamide, wherein the amount of ε-caprolactam is 200 ppm or less. When the resin composition comprises an EVOH-based resin and a nylon 6-based polyamide, contacting the resin composition with water can reduce the amount of ε-caprolactam.
